A good set of plans is the best way to get started, but not the only way. There are a lot of good, very detailed books on building a stripper, Stitch and glue, etc. I tend to think that they may provide too much information, so much that it can be discouraging. While it sounds like this isn't your first boat, if you find that the books are intimidating, remember that the link below has just enough information to build a stripper. (Very little, but enough)

The lines of the redwood canoe in the link are boring at best, but the process can be applied to any table of offsets that you can get your hands on. The idea that you can live without agonizing detail applies across the board for canoe size boats, not just strippers. SOF needs more detail than strip, and lapstreak needs even more.
And the problem with most strip boats, particularly at the outset of interest in the method, is that they are insanely pretty for tripping use, and often have very heavy detailing, and poor outfitting. It is all about the look.
Here again there is a problem with conventional -- 'wisdom'. The builder of a stripper has the option to spend an insane amount of time on a perfect finish. He also has the option of knocking out a nice serviceable boat with a reasonable effort.

Before we agree that stitch and glue canoes are flat bottomed, have a look around. There are more options. http://flo-mo.weebly.com/ is a good place to look. Tortured plywood can be surprisingly far from flat.
